8-2 skills practice adding and subtracting rational expressions

Answers

Answer 1

The expressions 3/x + 5/y and 3/(8p^2r) + 5/(4p^2r) are algebraic expressions

The simplified expressions are (3y + 5x)/xy and 13/(4p^2r)

How to solve the rational expressions?

From the complete question (see attachment), we have:

3/x + 5/y

Take the LCM

3/x + 5/y = (3y + 5x)/xy

Also, we have:

3/(8p^2r) + 5/(4p^2r)

Take the LCM

3/(8p^2r) + 5/(4p^2r) = (3 + 10)/(4p^2r)

Evaluate the sum

3/(8p^2r) + 5/(4p^2r) = 13/(4p^2r)

Hence, the simplified expressions are (3y + 5x)/xy and 13/(4p^2r)

17.1 equation of a circle evaluate homework and practice

Answers

Based on the calculations, the radius of this circle with the given equation is equal to 5 units.

Given the following data:

[tex]x^2+y^2+8x-6y+21=0[/tex]

The equation of a circle.

Mathematically, the standard form of the equation of a circle is given by;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where:

h and k represents the coordinates at the center.r is the radius of a circle.

Expanding the equation, we have:

[tex]x^2+y^2-2hx-2ky+(h^2+k^2-r^2)=0\\\\r=\sqrt{h^2+k^2}[/tex]

Comparing the terms, we have:

[tex]-2hx = 8x\\\\-2h=8\\\\h=\frac{8}{-2}[/tex]

h = -4

[tex]-2ky = -6y\\\\-2k=6\\\\k=\frac{6}{-2}[/tex]

k = 3.

Now, we can determine the radius:

[tex]r=\sqrt{-4^2+3^2}\\\\r=\sqrt{16+9} \\\\r=\sqrt{25}[/tex]

r = 5 units.

To the heated water 0.5 kg of water at t3 = 20° c is added. what is the final temperature of the water, in kelvin?

Answers

The final temperature of the water after addition to the heated water at 20° C in degree kelvins' is calculated as; 295.23 K

What is the Final Temperature?

We are given;

mass of the initial water; m₁ = 2.5 kg

specific heat capacity of water; c = 4189 J/kg.K

initial temperature of water; T₁ = 13.5 ⁰C

final temperature of the water; T₂ = 22.5 ⁰C

mass of the final water; m₂ = 0.5 kg

initial temperature of the final water; T₁,i = 20 ⁰C

If the system is isolated, then we have;

m₁*c*(T_f - T₂) + m₂*c*(T_f - T₁,i) = 0

c will cancel out to give;

[2.5T_f - (2.5*22.5)] + [0.5T_f - (0.5*20)] = 0

2.5T_f - 56.25 + 0.5T_f - 10 = 0

T_f = 66.25/3

T_f = 22.08°C = 295.23 K

Christopher runs a farm stand that sells apples and bananas. Yesterday christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163. 50. Today he sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76. 75. Determine the price of each pound of apples and the price of each pound of bananas

Answers

The equation computed shows that the price of apple is $2 and the price of banana will be $2.75.

How to compute the equation?

Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. This will be:.

35a + 34b = 163.50

He also sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76.75. This will be:

15a + 17b = 76.75

Equate both equations

35a + 34b = 163.50 ..... i

15a + 17b = 76.75 ...... ii

Multiply equation i by 15.

Multiply equation ii by 35

525a + 510b = 2452.50 .... iii

525a + 595b = 2686.25 .... iv

Subtract equation iii from iv

85b = 233.75

b = 233.75/85

b = 2.75.

The price of banana is $2.75.

The price of apple will be:

35a + 34b = 163.50

35a + 34(2.75) = 163.50

35a + 93.50 = 163.60

35a = 163.50 - 93.50

35a = 70

a = 70/35

a = 2

The price of apple is $2.

The National Response Framework (NRF) is a comprehensive guide developed by the United States Department of Homeland Security to facilitate effective response and recovery efforts during emergencies, disasters, and incidents. The NRF's five key principles, known as the "Five Mission Areas," outline the fundamental aspects of emergency management. These mission areas include:

1. Prevention: Activities aimed at preventing emergencies or disasters from occurring. This involves measures such as risk assessment, hazard mitigation, and public education to minimize the likelihood of incidents.

2. Protection: Actions focused on safeguarding individuals, critical infrastructure, and key assets from potential threats and hazards.

3. Mitigation: Efforts to reduce the impact and severity of disasters by implementing measures to minimize the potential damage and disruption caused by hazards.

4. Response: Immediate actions are taken to address and manage the consequences of an incident. This includes coordinating emergency response activities, mobilizing resources, conducting search and rescue operations, providing medical assistance, and ensuring public safety.

5. Recovery: Activities aimed at restoring affected communities and rebuilding the impacted areas after an incident. This includes facilitating the recovery process, providing assistance to individuals and businesses, restoring critical services, and rebuilding infrastructure.

In summary, scalable, flexible, and adaptable operational capabilities are integral to the National Response Framework's five key principles, as they enable effective emergency management and response during various incidents and disasters.
